The magical Montreal run continued on Friday night. Here's what went on.
Federer has won all seven career matches and taken all 16 sets against the 29-year-old Bautista Agut.
Roger Federer renewed his rivalry with David Ferrer and felt a tinge of regret after beating the Spanish veteran 4-6, 6-4, 6-2 in the third round of the Rogers Cup Canadian Open men's tennis championships.
Haase, playing in his first ATP World Tour Masters 1000 semi-final, did well to force a second-set tiebreak but Federer proved too much to handle as the Swiss fired down nine aces and dropped only nine points on serve.
Federer took the opening with both hands as he ruthlessly served out the set in the next game easily, clinching it 6-4.
"I'm happy I'm playing as well as I am this year on the match courts".
Bautista Agut twice held serve but crucially could not fire a shot on Federer's service game, who calmly dispatched the Spaniard on each occasion to seal the victory.

After breakout scintillating wins over Juan Martin del Potro, Rafael Nadal and Adrian Mannarino, in addition to having saved match points in his first round match, the young 18-year-old fell just short in a spirited contest with 20-year-old Alexander Zverev who outclassed and overpowered the Canadian 6-4, 7-5 in the quarterfinals.
The tension was palpable as both players sought to make a bit of history in their careers, and it looked as if Schwartzman would make a slow start again as he did against Donaldson.
Shapovalov put Mannarino in trouble with a big serve at 30-30, but he rushed an overhead to give the Frenchman the break point.
The first set was a disaster for Shapovalov. In the victory, Haase won 84 percent of his first serve points and 31 percent of his second serve points.
The Canadian broke immediately after a rain delay but Mannarino hit back in the next game.
However, it will be an uphill task for Haase in the semi-final, given Federer commanding display at the hard court tournament so far. A win will give help Federer reach his first final of the tournament since losing to Jo-Wilfried Tsonga in 2014 title match. Even after he fell behind by a set and a break early in the second set he never wavered and never even seemed to doubt that not only was he good enough to lock horns with the German, he was good enough to win.
